My Windows 10 computer has a EVGA GeForce GTX 1080 Founders Edition and Sony X900E (4K HDR TV 2017) connects to the graphics card by an HDMI cable. After I install the Creators Update, the HDR video technology is not working at all with Mass Effect Andromeda and other supported games. All drivers are up to data. I enable the native HDR in windows and go to full screen, the screen of game indeedly appears dull and grey while HDR is not detected in any way. Then I configure to use Nvidia color settings in NVIDIA control panel to fix the dullness problem but color becomes overly bright and it is hard to play. How can I fix the broken function?
The Windows 10 Creators Update, codenamed Redstone 2, feature the high dynamic range (HDR) and wide color gamut support for PC games and media, and the HDR can display a much wider range of colors on a TV display. However, the latest nvidia drivers (381.65) causes all sorts of HDR issues in Creators Update, such as HDR greyed out in display settings with my Samsung KS8000 TV, Custom ICC profiles/NVIDIA color settings are lost. To resolve it temporally, you have to do a clean install of older driver.
* Download the previous nvidia drivers onto your tablet or computer. Any old drives will do the job well actually, while the GEFORCE GAME READY DRIVER 378.92 version is the latest driver without any HDR issue.
* Double click on the 378.92-desktop-win10-64bit-international-whql.exe file, Choose Custom install, check Clean install box, and start the installation process.
* Then restart the system to continue installing the driver. Once it is finish, you are able to use the HDR feature while playing video game. Enjoy yourself.
